Formula & Methodology Behind the Calculation
The calculator implements the exact computation logic prescribed in the Income Tax Act, 1961 as amended for FY 2017-18:
1. Gross Total Income Calculation
GTI = (Salary + House Property + Business/Profession + Capital Gains + Other Sources) – (Exempt Incomes)
2. Deductions Under Chapter VI-A
Total Deductions = Section 80C (max ₹1,50,000) + Section 80D (medical insurance) + Other applicable sections
3. Taxable Income Determination
Taxable Income = GTI – Standard Deduction (₹40,000) – HRA Exemption – Chapter VI-A Deductions
4. Tax Calculation Based on Slabs
| Age Group | Income Range | Tax Rate | Surcharge |
|---|---|---|---|
| Below 60 | Up to ₹2,50,000 | 0% | – |
| ₹2,50,001 to ₹5,00,000 | 5% | – | |
| ₹5,00,001 to ₹10,00,000 | 20% | – | |
| Above ₹10,00,000 | 30% | 10% (if income > ₹50 lakh) 15% (if income > ₹1 crore) |
|
| 60-80 | Up to ₹3,00,000 | 0% | – |
| ₹3,00,001 to ₹5,00,000 | 5% | – | |
| Above ₹5,00,000 | 20% (₹5-10L) 30% (above ₹10L) |
Same as above |
5. Cess Calculation
Total Tax = (Income Tax + Surcharge) + 3% Education Cess
6. Rebate Under Section 87A
For FY 2017-18, rebate of ₹2,500 was available if taxable income ≤ ₹3,50,000 (reduced from ₹5,000 in previous year)

Interactive FAQ: 2017-2018 Tax Calculation
What was the standard deduction introduced in Budget 2018?
The Budget 2018 introduced a standard deduction of ₹40,000 for salaried individuals, replacing the previous transport allowance (₹19,200) and medical reimbursement (₹15,000). This was designed to:
- Simplify tax filing by reducing documentation
- Provide uniform benefit to all salaried taxpayers
- Compensate for the removal of specific allowances
Note: This was not an additional benefit but a replacement of existing exemptions.
How was HRA exemption calculated differently for metro vs non-metro cities?
The HRA exemption was calculated as the minimum of:
- Actual HRA received from employer
- For metro cities (Delhi, Mumbai, Chennai, Kolkata): 50% of basic salary
- For non-metro cities: 40% of basic salary
- Actual rent paid minus 10% of basic salary
Example: For a Mumbai-based employee with:
- Basic: ₹50,000/month
- HRA: ₹25,000/month
- Rent: ₹20,000/month
Exemption = min(25,000, 25,000, 20,000 – 5,000) = ₹15,000/month
